Alpha 7 Bug

Alpha 7 had a nasty bug where the game would crash when your tank is knocked out. Had to do with how the sector from which the knock-out hit came from was stored. Alpha 7.1 fixes this and adds some new updates to the campaign day map, but savegames from 7 will likely not transfer over to 7.1 since many of the variables in the campaign day map object have been changed.
